Abstract:
Objective To investigate the effect of pre-treatment of ginkgo biloba extract from portal vein on oxidative stress in liver surgery.Methods Sixty cases of hepatic portal occlusion for hepatectomy surgery in patients (38 males, 22 females, ASA grade Ⅰ or Ⅱ, cardiac function Ⅰ or Ⅱ, Child-Pugh class A), were randomly divided into three groups (n=20 each): portal vein injection group (group P), jugular vein injection group (group J) and control group (group C).Patients in group P were injected with ginkgo biloba extract injection 5 ml slowly from portal vein after freeing the portal vein, patients in group J were injected with ginkgo biloba extract injection 5 ml slowly from the jugular vein after freeing the portal vein, while patients in group C were injected with normal saline 5 ml slowly from the jugular vein after freeing the portal vein.Venous blood samples were drawn from jugular vein at the following time points: pre-occlusion ten minutes (T0), 1 h (T1), 6 h (T2), 24 h (T3) after reperfusion respectively, and then detected the levels of ALT, AST, tumor necrosis factor(TNF-α), manlondialdehyde (MDA) and the activity of superoxide dismutase (SOD).Results Compared with T0, the serum levels of ALT, AST, TNF-α and MDA at T1-T3 were significantly increased,the activity of SOD was significantly decreased in all groups (P＜0.05).Compared with group C, serum levels of ALT, AST, TNF-α and MDA at T1-T3 were significantly decreased, the activity of SOD was significantly increased in groups J and P (P＜0.05).Compared with group J, serum levels of ALT, AST, TNF-α and MDA at T1-T3 were significantly decreased, the activity of SOD was significantly increased in group P (P＜0.05).Conclusion The pre-treatment of ginkgo biloba extract from portal vein can increase the SOD activity, inhibit the activation of Kupffer cells, reduce the release of TNF-α, enhance the ability of anti-oxidative stress and produce significant protective effect on liver ischemia-reperfusion injury.
